The present invention relates to dust mops and the like and has. to dowith means for jointo the handle,'means for rotating thehead abouta'centrally disposedshaft and for locking the head in any one of a plu-This application is a continuation in part of applicants applicationSerial No. 436,358 filed March 26, l942, for Dust mops, which issuedPatent No. 2,325,598.

structures of similar types of to the applicant as In conventional mop'sthe locking elements, which must be pulled apart to unlock, comprises apair of platesrelatively rotatable about acommon axis and adapted eachto engage'the other by means of vertical apertures and correspondingstops in opposite plates. Whereas, my structure comprises a shortvertical collar having oppositely disposed notches in its face incombination with a transversely positioned pivot adapted to engage thenotches and to be automatically unlocked. Thus; the combination madepossible by the use of a vertical collar, including the mounting of thehandle on the collar, provides aunique and simplified structure incompact form.

One object of the invention is to provide a new and unique structure forjoining the head to the handle and for easily changing the head from thetransverse to the longitudinal position.

" Another object of the invention is to provide means for automaticallydisengaging'the locking elements in the'structure.

I -;A further object of theinvention is to'provide "a mop having'itshead'pivotally connected with the handle means forlimiting the rollingmovement of the head about the axis of the pivot.

) And another object of the invention is to provide the requiredstructure in a form combining details and simplicity with utility in amanner to facilitate the production and assembly of parts.

Other objects will be apparent from the drawing and specifications, "Inthe drawing:

Aapart notches 4 are formed in the face of the collar in a manneroppositely disposed notches adapted to engage the pivot 5, the axis ofeach pair of notches passing through the vertical axis of the collar 3.I

A tubular shaft 6 having a flange I at its lower end and a transverseopening 8 at its upper end is mounted in the aforesaid collar 3 with itslower end extending a substantial distance below the under side of thecollar and its upper end extending a substantial distance above theface'of the is mounted on the shaft In between flange Land the underside of the collar.

H With the tubular shaft 6 in place as heretofore indicated the handlelU-and head 2 are connected by forcing the shaft upward to a positionwhere its transverse opening Band openings in plates H register at thetop of the collar 3 and inserting pivot 5 through said openings.

It is to be noted that'collar 3, tubular shaft 6 and the handle If! invertical position have a common vertical axis and that the transverseaxis of pivot 5 and the transverse axis of each pair of the notches 4coincide with said common The handle I0 is provided with plates H at itslower endwhich plates fit over the outside of collar 3. Openings at thelower end of said plates to receive-a pivot 5 and cams l3- at the lowerend of the plates are positioned a substantial distance below theopenings 12 and are adapted to engage the adjacent plate I of the mannerto limit the movement of the head about the axis of pivot 5 and saidcams are adapted to lift said pivot out of a pair of the notches 4 whenthe handle is tilted to a vertical position as in Figures 3 and 4.
